Texture atlas merges textures as you describe. It does not explicitly change resolution. You could always use something like Photoshop's Automate tool, or countless other tools to resize the merged textures. OGL texture coordinates are normalized, so they don't care what the actual image size is. > Also is it able to change the texture format to jpeg or dds? No, but you could do this during the resize process, and then do a search and replace of your model files (depending on the format) to rewrite the image file extension. -- Chris 'Xenon' Hanson, omo sanza lettere.
